Single-axis analog Hall sensor for position and current sensing
The TLE4922XINFHALA1 is a single-axis Hall-effect sensor from Infineon's automotive-grade family, delivering an analog voltage output proportional to the magnetic field. Its ±400 mT sensing range covers most rotary position and current-sense applications in engine-bay and chassis domains. With an 8 kHz bandwidth, the sensor tracks fast-changing fields — suitable for synchronous motor rotor position or gear-tooth detection at moderate speeds. The analog output feeds directly into an MCU ADC without an external encoder interface.
Automotive temperature range and AEC-Q100 qualification
Rated for -40°C to 155°C operating temperature, the TLE4922XINFHALA1 spans the full under-hood automotive temperature envelope. AEC-Q100 qualification means it has passed the reliability stress tests (HTOL, ESD, latch-up) required for production-vehicle programs. The supply range of 4.5 V to 18 V covers both 5 V and 12 V automotive rails, including cold-crank dips. Maximum supply current is 7 mA, and the output can sink or source up to 8 mA — enough to drive the ADC input capacitance without a buffer.
PG-SSO-4-1 through-hole package for prototyping and low-volume builds
The 4-pin SIP-style PG-SSO-4-1 package (through-hole) is straightforward to hand-solder and rework, making the TLE4922XINFHALA1 a practical choice for prototype runs, repair stock, or low-volume production where a surface-mount reflow step is not justified. The supplier device package is PG-SSO-4-1 — a standard footprint with 2.54 mm pin pitch. No special socket or carrier is required; the part inserts into a standard 0.100-inch header footprint on the PCB.
